CO2 storage mechanisms in saline aquifers

Structural trapping

density difference between injected CO2 and formation water

Solubility trapping

CO2 dissolves in water

gravity separation: CO2 rich water has higher density

Residual (capillary) trapping

dependant on pore size and relative permeability

Mineral trapping

CO2 reacts irreversibly with rock minerals

CO2 storage

CO2 in the underground vs CO2 in the atmosphere

15+ years of R&D

knowledge

methodologies

tools (software, hardware)

regulation

Successful pilot and full size applications

More pilots for covering more geological variability and consolidation of achievements

Move to deployment to decrease CO2 emissions
